Just started invega shot 2 weeks ago

Does anyone else feel less motivated to do anything or is it just me? My voices slowed down, but I’m still seeing things which is the opposite of what I wanted. I’d rather hear my voices than not hear them. I don’t like the things I see. They’re scary and the people that live in the walls control my dreams most nights so I almost always have nightmares. I just got my second shot yesterday. I’m finding it more and more difficult to get motivated. Is anyone else experiencing this? Should I switch medications or continue to give invega a shot? Does it take a while to fully work?
